when the spindle unit shells are fixed by using the tip cones, the spindle unit shells are required to be placed between the two tip cones, then the two tip cones are controlled to move towards the directions close to each other, so that the tips of the tip cones are slowly inserted into the spindle unit shells to be fixed, the tips of the tip cones are difficult to be in the same straight line with the circle center of the spindle unit shells when the spindle unit shells with different sizes are fixed due to inconsistent sizes of the spindle unit shells with different types, and when the tip cones are inserted into the spindle unit shells, one side of the tip cones is easy to rub with the inner wall of the spindle unit shells for a long time, so that abrasion of the tip cones and the spindle unit shells is accelerated, and the service life is shortened;
When the processing center processes the outer side of the main shaft unit shell, some scrap iron cut by the processing center is easy to have magnetism due to friction and the like, some scrap iron with magnetism is easy to adsorb to the surface of the tip cone, when the tip cone and the main shaft unit shell are in contact and tightly pressed, the scrap iron is easy to be embedded into the surface of the tip cone under the action of extrusion, so that the mass distribution of the surface of the tip cone is changed, when the tip cone rotates at a high speed, the surface quality of the tip cone is uneven, dynamic unbalance of the tip cone can be caused under the action of centrifugal force, and the stability of the tip cone is influenced.
